Induction machines – Motor Factory

Error when exporting and solving a project in Flux Skew – Transient application

This issue occurs when the user input “Represented coil conductors” is set to All phases (ref.: FXM-15877).

Current Max is not respected in IMSQ Scalar control

In the scalar control for induction machines with squirrel cage, the imposed maximum current is not respected (ref.: FXM-15701).

Working Point - UfN – Error while saving the test

For induction machines with an outer rotor, when performing the computation of a working point by using the Accurate with 1

phase Mode, then if you save the test and then perform the computation of the working point by using the Fast test: the computation fails

If we use the inverse sequence: Fast > Save > Accurate, there is no error (ref.: FXM-15868).

IMSQ - Scalar Maps or Efficiency map (U,f) tests fails with hairpin winding technology

Sometimes, the tests Scalar Maps and Efficiency map (U,f) are not correctly solved with a hairpin winding configuration, like for the Motor M1 of the reference catalogue (ref.: FXM-15843).

Power balance of No-load working point

Sometimes, computation of the no-load working point (slip=0.1%) leads to a NaN (Not a Number) result. The computed amount of iron losses is not consistent with the power balance (ref.: FXM-12600).

Torque slip curve

Test results are not continuously consistent over a torque slip curve. This occurs with the test Performance mapping T(Slip) - induction machines with a skewed squirrel cage. When the user targets a working point as an added value to be computed with the whole Torque-slip curve, sometimes this additional working point doesn't belong to the curve (ref.: FXM-12599).
